If there's one thing French brands do particularly well it's those understated and timeless pieces that can be incorporated into so many different outfits. A.P.C. Atelier de Production et de Création's 'Cora' cardigan is spun from a lightweight merino wool-blend and has lustrous mother-of-pearl buttons running through the front. Leave your arms bare to highlight the crochet-inspired open-knit design on the sleeves.
